The engine was renamed from rg3d to Fyrox. There are multiple reasons for that:

• rg3d is hard to pronounce.
• It has 3d in it, which has become confusing after adding proper 2D support.
• It is not memorable - some random letters and numbers.

The new name is not ideal too, but it is somewhat memorable, easy to pronounce, and less confusing.

Meaning and origin

So what does the new name mean and how it was created? Originally I proposed Feox as a new name, but a lot of people from the community told me that is sound like it missing r letter, so I added it, and it became Ferox. As with any good name it was already taken, and I decided to change a single letter and the Fyrox was born.

After this somebody noticed, that the name is actually sounds like Fire + Ox, and BillyDM created the logo with the "flaming bull". This is an excellent example of community work!
